We report two cases in which adult patients with large and short patent ductus arteriosus with shallow/no aortic ampulla and associated pulmonary hypertension had the defects successfully closed percutaneously using Amplatzer devices designed for atrial septal defect occlusion. The defects were stretched with a sizing balloon for optimal ductal size determination and device selection. Surgical treatment for associated discrete membranous subaortic stenosis was deferred in one patient because of significant gradient reduction in the left ventricular outflow tract after ductal occlusion. The technique of this novel approach and its possible advantages are discussed.
我们报告了两例成年患者，他们患有粗大且短的动脉导管未闭，主动脉壶腹浅或无，伴有肺动脉高压，使用专为房间隔缺损封堵设计的Amplatzer装置经皮成功闭合了缺损。用测量球囊扩张缺损以确定最佳导管尺寸并选择装置。一名患者因动脉导管封堵后左心室流出道压力阶差显著降低，因此推迟了对相关的局限性膜性主动脉瓣下狭窄的外科治疗。本文讨论了这种新方法的技术及其可能的优点。
